Changes in version 2.0.4 (2025-12-15)                  

Bug fixes

  - Add internal function so that real-data.Rmd vignette will fail
    gracefully if data file cannot be downloaded
    (https://github.com/ropensci/dwctaxon/pull/123). This should ensure
    compliance with CRAN policy.

                 Changes in version 2.0.3 (2023-12-13)                  

Bug fixes

  - Don't require that all values of a reference column be unique when
    matching values, instead only require that the matched values be
    unique. This means it is now possible to use (for example)
    dct_fill_col() to fill acceptedNameUsageID based on scientificName
    even if scientificName contains some duplicated values, as long as
    those don't match any values in the match_from column
    (https://github.com/ropensci/dwctaxon/pull/97)

Documentation

  - Add documentation of extra_cols option in dct_options()
    (https://github.com/ropensci/dwctaxon/pull/99)

CRAN policies

  - Add a check for an internet connection and valid URL when
    downloading files to ensure compliance with CRAN policy
    (https://github.com/ropensci/dwctaxon/pull/94)

                 Changes in version 2.0.2 (2023-05-30)                  

Other

  - Save options with options() and restore at end of each example
    (https://github.com/ropensci/dwctaxon/commit/c9a3c3b432854521d876c2492931ed6189a7abca)

                        Changes in version 2.0.1                        

Other

  - Use /dontrun{} to skip examples that intentionally cause errors
    (https://github.com/ropensci/dwctaxon/pull/89)

  - Save user settings with dct_options() and restore at end of each
    example (https://github.com/ropensci/dwctaxon/pull/91)

                        Changes in version 2.0.0                        

Breaking Changes
